Render layer causing image "shearing" in video sequence editor
As cegaton mentionend, the file you uploaded won't produce such problems on my side neither:

Though I had to disable your dust layers to get another result than lots of white:



However, I suppose, it's a driver problem on your side. I already had a graphics cards driver problem with Blender. The developers helped me out to find out whether the problem is one with the driver.

You should use the opengl32.dll from http://download.blender.org/ftp/sergey/softwaregl/ and place it next to blender.exe as described by sergey to find out if the problem is your driver. Beware, that Blender might be very slow while using this wrapper dll as everything is done on CPU only without using your graphics card.
